New kid on the block? Or learning how to mod Fable?
Here are some links to tutorials and information gathered in one post.
Some of the tutorials are located on this forum, others are external.

Important notice:
Projectego.net switched the software that runs their forum, hence a couple of links are dead now.
No I'm not going to fix that. Too much work.
But if anyone else is up for it, feel free to pm me.DarkONI was so kind to find and replace the dead links, or at least most of them!
The ones that couldn't be fixed are marked // Unrecoverable Link.Thanks!!!

Lesson 1
Make backups of your gamefiles!!!
You don't have to, but I'd recommend to do this when you start messing with them.
Of course you can always reinstall the game, but that takes a lot more time then replacing the screwed files with the backups.

By default these files can be found in the subfolders in:C:\Program Files\Microsoft Games\Fable - The Lost Chapters\Data

How to make a backup:
Click one a file once. Press 'ctrl' and 'c'. Then press 'ctrl' and 'v'.

#Detailed instructions on making a backup.# Making backups with ShadowNet is also very easy, see below for more details.

Help! I didn't make backups... now my game won't run.# You can get the gamefiles of your fable disc[s].
Read this to find out how. Check the second spoiler.# You can also reinstall the game.
Uninstall Fable, and check if there are any files left behind here: C:\Program Files\Microsoft Games\Fable - The Lost Chapters\ [if you installed to a different directory check there of course]
If there are any files, delete them before making a fresh install.

#ShadowNet
ShadowNet is Fable Explorer, but with more capabilities. If this works for you - use it instead of Fable Explorer 4.1
It has a search function, and a build in backup function. (Richt-click on a file in the top right corner, and select Backup. To restore: right-click and select Restore)
ShadowNet can also merge multiple fmp's into a single fmp, I used this to make the NewItemPacks.
It also has the capability to make fmp's with script.bin entries - something that FableExplorer 4.1 can't.->You need .net 3.5, and update your DirectX (and if it doesn't run you might need this.)->Also download the latest def.xml here and put it in the Shadownet folder.

#Fable Explorer
Fable Explorer is your basic tool for editing, and using or making mods for Fable.
It can edit almost all gamefiles Fable uses. You need it to create and load FMP's (Fable Mod Package).
Info from the wiki here.
Fable Explorer needs the .net framework 2.0 (you can also use the installer).
-> Here you'll find a version with a search function - which is still beta, but it works fine for me.

Basically, I took FableExplorer and AlbionExplorer and fused them together and added a 3D region editor. I also tried to improve the user interface whenever possible.
There are bugs in the application. I'm not going to pretend they aren't there, 'cause they are. If the application crashes while you are using it do not come here shouting "It cr4shes!1!". That's completely pointless. I have no time for that crap.Requirements
* Knowledge of FE and 3D modelling packages, such as Blender
* .NET 2.0
* DirectX 9.0c
* Microsoft Visual C++ SP1 Update
* A pc that wasn't built last decade

#Albion Explorer
With Albion Explorer you can edit the world of Fable (the levelscripts). Buildings, chest, enemy's etc.
To use this, you also need the FreeRoam App (see below). Basic help here.
Albion Explorer needs the .net framework 2.0 (you can also use the installer).

#FreeRoam App
This application extracts the FinalAlbion.wad into a bunch of tng's (which contain the levelscripts)
It can patch it so you lose the normal borders in the game.
Information on how to use it here.FreeRoam instructions for Vista
#FreeRoam FMP
This isn't exactly an application, but it can serve as a substitute for the FreeRoam App.
If you don't want to extract your FinalAlbion.wad or having trouble with the free roam app you can use this.
You can also still edit tng's with this method.

#Notepad
Notepad is found on every pc with Windows.
You can use this text editor for scripting (editing tng files), changing .bncfg files (see #Editing the hero size)
and changing the FinalAlbion.qst (see #Play Quests again after completion).
There are alternatives which have a bit more functions such as Notepad++ and EditPadLite.

Fable modding for XBox
Some stuff works the same as for PC, other stuff doesn't.
Can't tell you much more about it, since I havn't done it myself.
You'll find some info here// Unrecoverable Link and here.
General information and tutorials on modding your xbox can be found here.

->If anyone has links to usefull info on this subject, please post them in this thread.

Editing Textures
To edit textures you need something better then Paint.
Obviously Photoshop is the standard nowadays,
but there are some alternatives that are pretty good, and free to use.
One of my favorites is Paint.net, which sits somewhere between Paint and Photoshop.
Then there's The Gimp which is very similar to Photoshop in it's capabilities.

Editing Models
First off: Editing models isn't very hard, but an appliction like 3ds Max isn't like Word or even Photoshop.
It takes a little bit more to learn the basics. So if you want to edit models, prepare to put some time in it.
But: It is worth it!

Editing Animations and the CAppearanceDef
#This is stuff for more advanced modders. If you don't consider yourself one, don't mess with it.

#It's not possible to create new animations and import them in the game (the graphics.big).

#However it is possible to add animations from other npc's to the hero, or swap the hero's model and make it use other animations.
This stuff is handled in the CAppearanceDef, and Silver wrote an application to work with it. You'll also find some instructions there.
As said above: this isn't easy and I only know of a couple of people who've created mods with the app;
Silver (Express yourself), Bluetooth (Staff Animations) and Marcopolo (Balverine Transformation mod).
